MRI Study of Caudate Nucleus Volume and Its Cognitive Correlates in Neuroleptic-Naive Patients With Schizotypal Personality Disorder
(American Psychiatric Publishing, 2002)
Objective: “Cognitive” circuits anatomically link the frontal lobe to subcortical structures; therefore, pathology in any of the core components of these circuits, such as in the caudate nucleus, may result in neurobehavioral ...
Anterior limb of the internal capsule in schizophrenia: a diffusion tensor tractography study
(Springer Science + Business Media, 2012)
Thalamo-cortical feedback loops play a key role in the processing and coordination of processing and integration of perceptual inputs and outputs, and disruption in this connection has long been hypothesized to contribute ...
Shape of caudate nucleus and its cognitive correlates in neuroleptic-naive schizotypal personality disorder
(Elsevier BV, 2004)
Background: We measured the shape of the head of the caudate nucleus with a new approach based on magnetic resonance imaging (MRI) in schizotypal personality disorder (SPD) subjects in whom we previously reported decreased ...
A Unifying Approach to Registration, Segmentation, and Intensity Correction
(Springer Science + Business Media, 2005)
We present a statistical framework that combines the registration of an atlas with the segmentation of magnetic resonance images. We use an Expectation Maximization-based algorithm to find a solution within the model, which ...
Quantitative Volumetric MRI Study of the Cerebellum and Vermis in Schizophrenia: Clinical and Cognitive Correlates
(American Psychiatric Publishing, 2016-09-14)
Objective: Recent evidence suggests that the cerebellum may play a role in higher cognitive functions and, therefore, may play an important role in schizophrenia. Method: The authors used magnetic resonance imaging to ...
Shape abnormalities of caudate nucleus in schizotypal personality disorder
(Elsevier BV, 2009)
Background: Previously, we reported abnormal volume and global shape in the caudate nucleus in schizotypal personality disorder (SPD). Here, we use a new shape measure which importantly permits local in addition to global ...
An In Vivo MRI Study of Prefrontal Cortical Complexity in First-Episode Psychosis
(American Psychiatric Publishing, 2005)
Objective: The purpose of this study was to investigate abnormalities in the surface complexity of the prefrontal cortex and in the hemispheric asymmetry of cortical complexity in first-episode patients with schizophrenia. ...
A diffusion tensor imaging study of the anterior limb of the internal capsule in schizophrenia
(Elsevier BV, 2010)
Introduction—Frontal-subcortical cognitive and limbic feedback loops modulate higher cognitive functioning. The final step in these feedback loops is the thalamo-cortical projection through the anterior limb of the internal ...
Prefrontal Gray Matter Volume Reduction in First Episode Schizophrenia
(Oxford University Press (OUP), 2001)
Functional measures have consistently shown prefrontal abnormalities in schizophrenia. However, structural magnetic resonance imaging (MRI) findings of prefrontal volume reduction have been less consistent. In this study, ...
Prefrontal cortical thickness in first-episode psychosis: a magnetic resonance imaging study
(Elsevier BV, 2004)
Background: Findings from postmortem studies suggest reduced prefrontal cortical thickness in schizophrenia; however, cortical thickness in first-episode schizophrenia has not been evaluated using magnetic resonance imaging ...
